A module may include any number of sub-modules, but each sub-module may belong to only one module.

Note

The names of all standard modules and sub-modules must be unique.

YANG data models can be represented in a hierarchical, tree-based structure with nodes, which makes them

more easily understandable. YANG defines four nodes types. Each node has a name, and depending on the

node type, the node might either define a value or contain a set of child nodes. The nodes types (for data

modeling) are:

• leaf node - contains a single value of a specific type

• list node - contains a sequence of list entries, each of which is uniquely identified by one or more key

• leaf-list node - contains a sequence of leaf nodes

• container node - contains a grouping of related nodes containing only child nodes, which can be any of
